Description

Device and system for plant growth

Technical Field

The present invention relates to growing plants. More particularly, the present invention relates to devices, systems and methods for hydroponic germination of plants.

Background

In recent years, the cultivation of hydroponic plants has been increasingly applied to a wide variety of fields. Indoor gardening is one such area that has rapidly developed due to the growing demand. The indoor plant growing device and the indoor plant growing system can be used by enterprises such as restaurants and the like or private individuals.

One such indoor plant growing apparatus is disclosed in applicant's patent application EP 3251499a1 which discloses a hydroponic plant growing cabinet optimised to enable simple and easy hydroponic cultivation of plants in a limited area.

European patent application EP 3087831 a1 discloses another houseplant growing system. The system is low in cost, simple, and can be used in, for example, homes, restaurants, and schools to grow vegetables, flowers, and other plants.

Such indoor plant growing apparatus can typically grow plants from seeds to fully mature plants over a period of days or weeks. Advantageously, the entire process can be performed by the device with little user intervention required.

Indoor plant growing apparatuses generally use a specific medium for storing seeds and subsequent germination of the seeds while supporting seedlings and plants thereafter.

German utility model DE 202014101486U 1 discloses a cartridge for use inside a hydroponic garden apparatus. The cartridge includes a growth medium including a cover configured to removably cover an upper surface thereof, the cover being comprised of a material that is opaque to blue light of about 400 to 500 nanometers and red light of about 600 to 700 nanometers.

Disclosure of Invention

It is an object of the present invention to provide an improved and simple to use apparatus and system for hydroponic plant growth. It is another object of the present invention to disclose a plant growing apparatus that is biodegradable and simple to use. It is a further object of the present invention to describe a device that can be used with a hydroponic plant growing cabinet.

In a first embodiment, a cartridge (pod) for hydroponic plants is disclosed. The cartridge includes a body including a top surface, a bottom surface, and at least one side surface. The side surface connects the top surface and the bottom surface. The body includes a recess. The contour of the top surface of the body is greater than the contour of the bottom surface of the body.

The cartridge described herein is particularly advantageous for preserving seeds until germination begins, and for supporting seedlings and plants thereafter. The shape of the box, characterized by a greater profile of the top surface than the bottom surface, may advantageously allow it to be placed in the opening and to be kept supported without additional support elements. In other words, the present device does not require the use of a support cup made of plastic or similar non-biodegradable material. The shape is also characterized by a circumscribed circle diameter of the top surface that is greater than a circumscribed circle diameter of the bottom surface.

The top, bottom and side surfaces may not be completely smooth because the material of the box may contain fibers, resulting in a rough surface. In this case, the surface may be understood as an average smooth surface.

More than one side surface can be provided. For example, in some embodiments, the body may comprise at least one of a truncated cone shape and a truncated pyramid shape. In the case of a truncated cone, the side may comprise one surface. Conversely, for a truncated pyramid, the side surface may include multiple surfaces connected at an angle.

In addition to supporting the box in a hanging position (which is advantageous for growth of hydroponic plants because the roots generally require free space under the box), the shape of the box is advantageous for root growth, which can reach the spacious space after growing a shorter distance than a straighter shape such as a simple cylinder.

In some embodiments, the side surface may be symmetrical with respect to an axis connecting the center of the top surface profile and the center of the bottom surface profile. Such a symmetrical box shape may be easier to manufacture and handle.

In some embodiments, the side surface may substantially correspond to a surface of rotation created by a line segment rotated about an axis connecting the top surface contour center and the bottom surface contour center. The angle between the line including the line segment and the axis may be 5 to 60 degrees, preferably 5 to 45 degrees. In other words, the flank may substantially correspond to the side surface of a truncated cone having the above-mentioned angle. Such an angle may ensure sufficient support when the box is suspended for the plant growing process, while still maintaining a compact shape that is most suitable for plant growth.

In some embodiments, the ratio of the top surface profile to the bottom surface profile may be between 1.2 and 3, preferably between 1.5 and 2. The same ratio can be applied to the diameter of the circumscribed circle of each surface, respectively. Such proportions may also facilitate the box to support itself when suspended and to maintain a compact and optimal shape for seed storage, germination and plant growth.

In some embodiments, the cartridge body may further comprise a protective layer. The protective layer may form a barrier between at least a portion of the recess of the body and the surrounding medium. The surrounding medium may refer to the surroundings of the cartridge, that is to say the air and its nearby objects. Forming such a barrier may advantageously separate the recess and its contents from the surrounding environment. Preferably, seeds may be placed within the recesses and the protective layer may isolate them from the surrounding air, which may have high humidity and may lead to premature germination. Preferably, the protective layer is placed in a manner that prevents or severely limits the exchange of air from the surroundings inside the recess, across at least a part of the recess.

In some embodiments, the protective layer is soluble in a liquid. Preferably, the protective layer is soluble in water. This property has a significant effect on ensuring that the seeds do not germinate prematurely. When exposed to water (or nutrient solution), the protective layer melts, allowing the seeds to begin to germinate.

In some embodiments, the protective layer may be hygroscopic. As mentioned above, this is particularly advantageous for preventing premature germination of seeds placed in the recesses of the body.

In some embodiments, the protective layer may be configured to prevent germination of seeds placed in the recess of the body. However, it is preferred that the protective layer is readily soluble so that germination can begin when the cartridge is placed into a plant growing apparatus (e.g. a plant growing cabinet) from a storage location. When the protective layer is intact, germination can be prevented. This can be achieved either by the chemical structure of the protective layer, by its own topology, or by placing it near the recess of the cartridge body.

In some embodiments, the protective layer may have a substantially circular cross-section. In certain such embodiments, the protective layer may have a surface area that substantially corresponds to a truncated sphere cylinder. In other words, the protective layer may comprise a hollow solid or semi-solid. For example, the protective layer may comprise a capsule or a portion of a capsule within which the seeds may be placed. This may be particularly advantageous as it may create and maintain isolated physical conditions for the seeds within the protective layer.

In some embodiments, the protective layer may have a thickness of 0.01 to 0.4 cm. This may be an optimal thickness to ensure that the seed does not start to germinate prematurely, but once germination has begun, to allow the protective layer to melt or peel.

In some embodiments, the protective layer may be biodegradable. This is particularly advantageous as it can reduce waste associated with plant growth and make efficient use of resources. In a preferred embodiment, the protective layer may comprise gelatin. This is much more advantageous than using other water soluble substances. Water-soluble substances are often not completely dissolved by water, leaving lumps and marks which can remain on the box and subsequently eventually fall onto the growing plant or enter sensitive parts of the hydroponic plant growing apparatus (once the box is placed therein and has started to germinate) and cause failure.

In some embodiments, the protective layer may comprise an enclosed space. As mentioned above, wrapping the seeds in a protective layer is the most effective and simple way to prevent their premature germination. Furthermore, the protective layer and the casing can be manufactured and stored separately and only be combined immediately before the start of the intended germination. In this way, the seeds can be protected and isolated until the protective layer dissolves or dissipates (preferably due to the initial watering). In certain such embodiments, the enclosed space may include at least one atmospheric parameter that is independent of an ambient atmospheric parameter surrounding the isolation layer. The parameters may include humidity, air pressure, air temperature, and/or the like. Advantageously, this may allow maintaining optimal physical parameters of the seeds during storage and before germination starts.

In some embodiments, the cartridge may comprise mineral wool. In other embodiments, the cartridge may comprise a polyadic acid. In other embodiments, it may comprise jute fibers. In other embodiments, the box may include floral foam. Such nonwoven materials are particularly advantageous as plant growth media. They can allow the development and flourishing of hydroponic plants.

In some embodiments, the cartridge may further include a water-soluble adhesive. That is, the case may be partially stuck together, or a water-soluble adhesive may be applied to the outer surface (preferably the side) of the body thereof. This helps to maintain the integrity of the box during storage and further prevents premature germination by isolating the interior of the box from moisture.

In some embodiments, the cartridge may be biodegradable. As mentioned above, this is advantageous in reducing waste of resources and optimizing energy expenditure associated with manufacturing and waste management.

In some embodiments, the cartridge may further comprise a support layer. The support layer may be configured to maintain the integrity of the cartridge. That is, the support layer may serve to further ensure that the cartridge can be supported when suspended for plant growth. The support layer may be adjacent to the top surface.

In some embodiments, the cartridge may comprise two connected cylinders. The top surface may be located on the first cylinder and the bottom surface may be located on the second cylinder. In other words, the cartridge may comprise a solid T-shape with the thicker portion at the top and the thinner portion at the bottom. This shape allows the cassette to be hung on top of it. In contrast to known prior art embodiments, the cassette of the present application need not include a separate support, which is typically made of plastic and can be supported with its own weight. This may advantageously reduce the use of plastic or the need for additional components in the growth of hydroponic plants.

In a second embodiment, a cartridge for growing plants is disclosed. The cartridge includes a body including a top surface, a bottom surface, and at least one side surface. The side surface connects the top surface and the bottom surface. The cartridge body further comprises a protective layer. The body of the cartridge includes a recess. The protective layer forms a barrier between at least a portion of the recess and the surrounding medium.

The cartridge of the second embodiment advantageously isolates or protects seeds placed in the recess in the body from surrounding media such as air or nearby objects. As long as the protective layer is present and intact, the seeds can be prevented from germinating. This may be achieved by at least partially limiting the exposure of the seeds to a humid environment.

Although the second embodiment differs from the first embodiment (since the geometric limitations of the cartridge are optional), both embodiments, as well as all alternative embodiments of either, may be combined and should therefore be construed by the person skilled in the art as being applicable to either of the two separate embodiments.

In some embodiments, the protective layer may form a barrier over the recess of the body. This may be a partial barrier, so that the protective layer only covers the top of the recess. Conversely, the protective layer may also wrap the seed. Both embodiments are possible and advantageous. In the first case, the protective layer may preferably be curved, the maximum diameter of which preferably exceeds the diameter of the recess.

In some embodiments, the protective layer is soluble in a liquid, preferably water. Thus, the user can water the box (or have it automatically water) once it is desired that the seeds begin to germinate.

In some embodiments, the protective layer may be hygroscopic.

In some embodiments, the protective layer may be configured to prevent premature germination of seeds placed within the recess of the body.

In some embodiments, the protective layer may have a substantially circular cross-section. In certain such embodiments, the protective layer may have a surface area that substantially corresponds to a truncated sphere cylinder. For example, the protective layer may comprise a surface area substantially corresponding to the capsules or truncated capsules. The seeds can then be safely placed inside the capsule or under the dome of a truncated capsule. This prevents them from sprouting and also prevents them from migrating within the cartridge.

The protective layer may have a thickness of 0.01 to 0.4 cm. As mentioned above, this may include an optimal thickness to prevent premature germination and allow it to germinate immediately once needed.

The protective layer may preferably be biodegradable. In a preferred embodiment, the protective layer may comprise gelatin.

In some embodiments, the protective layer may comprise an enclosed space. This allows the seeds to be optimally protected from the surrounding environment, as described above. The enclosed space may include at least one atmospheric parameter independent of an atmospheric parameter of an environment surrounding the isolation layer.

In some cases, the protective layer may be configured to secure the seed within the enclosed space. In other words, the seed may be placed in a protective layer and not allowed to move unless within its enclosed space. The protective layer may also prevent the seeds from moving within the cartridge when the cartridge is not closed. In such embodiments, the protective layer may form a cap or dome on the seeds and prevent them from migrating out of or within the cartridge.

In some embodiments, the profile of the top surface of the body may be greater than the profile of the bottom surface of the body. Similarly, the diameter of the circumcircle of the top surface may be larger than the diameter of the circumcircle of the bottom surface.

In some embodiments, the body may include at least one of a truncated cone shape and a truncated pyramid shape.

In some embodiments, the side surface may be symmetrical with respect to an axis connecting the center of the top surface profile and the center of the bottom surface profile.

In some embodiments, the side surface may substantially correspond to a surface of rotation generated by a line segment rotated about an axis connecting the centers of the top and bottom surface profiles, and an angle between a line including the line segment and the axis may be 5 to 85 degrees, preferably 5 to 45 degrees.

In some embodiments, the ratio of the top surface profile to the bottom surface profile may be between 1.2 and 3, preferably between 1.5 and 2.

In some embodiments, the cartridge may further comprise a support layer. The support layer may be configured to maintain the integrity of the cartridge. The support layer may be adjacent to the top surface.

The cassette may comprise two connected cylinders and the top surface may be located on a first cylinder and the bottom surface may be located on a second cylinder.

In some embodiments, the protective layer may be mounted to a body of the cartridge body configured to withstand a separation force of at least 0.01 newtons, preferably at least 0.1 newtons. In other words, the protective layer is attached to the body of the cartridge in such a way that it does not easily detach due to inversion (and under the action of gravity) or upon shaking (due to transport or similar reasons). This retention can be achieved, for example, by making the maximum diameter of the protective layer slightly larger than the diameter of the recess of the cartridge body and forcing them together. The elasticity of the protective layer and/or the cartridge as well as the friction may provide sufficient retention.

In a third embodiment, a system for growing plants is disclosed. The system includes a cartridge including a body including a top surface, a bottom surface, and at least one side surface. The side surface connects the top surface and the bottom surface. The system also includes a socket including an opening configured to receive the cartridge body. The profile of the bottom surface is smaller than the profile of the socket opening. The profile of the top surface is greater than the profile of the socket opening.

The present system is preferably configured to provide conditions suitable for plant germination, growth and reproduction. The cartridge may be received in a receptacle so that a portion thereof may be suspended. In this way, the seeds, preferably placed in the box, can germinate and the roots can have room for growth.

The socket may comprise a cup, such as a ceramic cup. The box and receptacle can receive a plant growing apparatus (e.g., applicant's plant growing cabinet) where plants can be grown through a plurality of boxes and cups.

Advantageously, the present system provides a cartridge that fits into a socket without the need for additional support elements, such as plastic baskets, to hold the cartridge in place. The shape of the box itself allows it to be supported when inserted into the socket. There may also be other reinforcing elements, such as those described above and below, but the present system preferably includes biodegradable components and does not have disposable or reusable components that are easily accidentally discarded.

In some embodiments, the socket may further comprise a socket cavity accessible through the socket opening. That is, the socket cavity may open into a larger space, which may be contained within the socket. In other words, the socket cavity may be closed by the socket body with the only opening through the socket opening. For example, the receptacle may comprise a container (also referred to as a cup) as shown in fig. 4a and 4 b.

In some such embodiments, the system may be configured to limit light from reaching the socket cavity when the cartridge is placed in the socket. This can be achieved by providing a tight fit between the cartridge and the outlet opening, in particular by providing a shape of the cartridge that is capable of tightly fitting and supporting its weight.

In some embodiments, the ratio of the body portion of the cartridge having a diameter smaller than the outlet opening to the body portion of the cartridge having a diameter larger than the outlet opening is at least 5, preferably at least 8, for example at least 10. In other words, a substantial portion of the body of the cartridge may pass through the outlet opening, only about one fifth, preferably about one eighth, for example about one tenth, remaining above the outlet opening when the cartridge and outlet are assembled together. This may be advantageous to isolate a large portion of the surface area of the cassette from the light to avoid algae growth. The cassette may be configured in such a way that the remaining part is able to support the weight of the suspended cassette. Additional reinforcing elements may also be present, as described in further detail below.

In some embodiments, a portion of the cartridge may be configured to protrude above the opening when the cartridge is assembled to the receptacle. The maximum height of the protruding cartridge portion may comprise at least one of 1 mm and the overall height 1/10 of the cartridge. The projections may serve as a support for the cassette hanging over the opening of the receptacle and further allow the seeds placed in the cassette to be exposed to light once germination has begun (prior to germination, the illumination of the seeds is preferably limited).

In some embodiments, the system may further include a protective layer. The protective layer may be configured to fit into a recess of the cartridge body. The protective layer may be used to separate seeds placed in the recess of the cartridge body or in the protective layer itself from the external environment. For example, the protective layer may insulate the seeds from ambient humidity, which may otherwise cause premature germination.

In some embodiments, the protective layer may include a capsule configured to encapsulate the seed. That is, the seeds may be placed within the protective layer and stored separately from the cartridge and receptacle. When it is desired that a plant be grown, the protective layer containing the seed may be engaged with the cartridge (preferably placed in a recess in the cartridge) and the cartridge may also be engaged with the receptacle. Furthermore, the socket may be placed in a plant growing apparatus where plants may grow autonomously or almost autonomously.

In some embodiments, the system may further comprise a support layer. The support layer may be configured to maintain the integrity of the cartridge. The support layer may preferably comprise a biodegradable material which may help to stiffen the cassette when suspended within the receptacle.

The support layer may be configured to be adjacent to both the cartridge and the outlet. In other words, the support layer may be disposed around or adjacent a portion of the cartridge body and also adjacent a portion of the outlet opening. This may be advantageous in that it enhances the structural integrity of the cartridge and increases the support between the cartridge and the socket.

In certain embodiments, the support layer can be configured to surround at least a portion of the cartridge body until the contour of the body equals the contour of the outlet opening. That is, the support layer may preferably be placed on the periphery of the portion of the cartridge that protrudes above the outlet opening when the cartridge and outlet are assembled together. In this way, the support layer can help prevent algae from growing on portions of the cassette that are exposed to the surrounding environment, particularly to light.

In certain embodiments, the support layer can include an aperture adjacent at least a portion of the top surface. That is, the support layer may cover all of the surface area of the cartridge that protrudes above the outlet opening, leaving a hole for plant growth.

In certain embodiments, the protective layer may be configured to form a barrier between the pores and the surrounding medium. That is, the holes may be further covered by a protective layer to avoid premature germination. When germination is planned to begin (e.g., by the process of initiating watering), the protective layer may dissolve or dissipate.

The cartridge of the present system may be as described in the above embodiments.

The system may also be configured for use with a hydroponic plant growth cabinet. That is, the box and receptacle may be mounted together and placed within such a plant growing cabinet. There, appropriate lighting conditions and appropriate watering can be applied so that seeds placed in the box can germinate and plants can grow in the box with the root system extending into the sockets.

In a fourth embodiment is disclosed the use of the cartridge described in the above embodiments for hydroponic cultivation of plants. The use may also include placing the cartridge into a hydroponic plant growth cabinet.

Detailed Description

Fig. 1a and 1b show an embodiment of a cassette for plant growth in side and bottom views, respectively.

The case 1 includes a main body 2. The case 1 includes a top surface 4 at the top of the main body 2. The box 1 further comprises a bottom surface 6, correspondingly located at the bottom of the body 2. The side surfaces 8 connect the top surface 4 and the bottom surface 6 and extend around the body 2. The side surface may comprise one or more surfaces. For example, the side surface may include a smooth tapered surface. In another example, the side surface 8 may include a plurality of engagement planes, such as frustoconical surfaces.

There may be a plurality of sides 8 that are not directly joined to each other. For example, the cartridge 1 may comprise a solid "T" shape comprising two cylinders of different diameters joined together. In this embodiment, the side surface 8 may include both side surfaces of two cylinders. The top surface 4 may then comprise the top surface of one cylinder and the bottom surface 6 may comprise the bottom surface of another cylinder.

The top surface 4 comprises a larger profile than the bottom surface 6. That is, the top surface 4 has a larger track than the bottom surface 6. Typically, the surface area of the top surface 4 is also greater than the surface area of the bottom surface 6. However, this surface area requires calculation of the area comprising the recess 10, the recess 10 typically being located in the top surface 4.

The cartridge recess 10 may be a circular or differently shaped recess. Its height may be at least 1/10 the height of the cartridge 1. The recess 10 can be used for placing seeds into the cartridge 1.

Fig. 1a shows lines a and B, which in the case of their substantially circular shape correspond to the diameters of the top surface 4 and the bottom surface 6, respectively. When they are not circular, the line a and the line B may respectively correspond to the diameters of their circumscribed circles. The length of line a is greater than the length of line B. This corresponds to the contour of the top surface 4 being greater than the contour of the bottom surface 6.

Fig. 1b shows a bottom view of the cartridge 1. The bottom surface 6 and the top surface 4 are visible. They are shown as circles in fig. 1b, but this is exemplary as they may also comprise different shapes, for example polygons. The top and bottom surfaces may also be shaped differently. Lines a and B are also shown in the bottom view. Consistent with the foregoing, the length of line a is greater than the length of line B (a > B).

Fig. 2a and 2b show an embodiment of a cartridge for plant growth comprising a protective layer 12.

Fig. 2a shows a cartridge 1 with a recess 10 (for exemplary purposes, the shape here differs from fig. 1 a). The protective layer 12 forms a barrier between the cassette recess 10 and the surrounding medium. In other words, the protective layer 12 separates the interior of the recess 10 from the surrounding environment. One or more seeds 16 are shown in the recess 10, protected by the protective layer 12. The protective layer 12 is generally adapted to prevent premature germination of the seeds 16 before the cartridge 1 is placed in a hydroponic plant growth cabinet available for plant growth. This essentially means that the protective layer 12 ensures that the seed 16 remains in the recess and limits exposure and moisture caused by the ambient medium.

The protective layer 12 is shown in fig. 2a as a semi-circle. This may be an embodiment of the protective layer. However, the protective layer 12 may also comprise a layer extending across all recesses 10 and/or all top surfaces 4.

Preferably, the protective layer is made of a water-soluble material. For example, the protective layer may comprise gelatin, such as a gelatin capsule or a portion of a gelatin capsule.

In fig. 2b, the protective layer encapsulates or encapsulates the seed 16. This is a preferred embodiment as it may be advantageous to allow the seeds 16 to be stored separately from the cartridges and to place them in the cartridges before the seeds 16 germinate. In other words, the protective packaging layer 12 containing the seeds 16 can be stored separately from the case 1. In this way the cartridge 1 can be made replaceable, since a plurality of different seeds can be placed in the recess 10 in the encapsulating protective layer 12. Thus, the cartridge 1 and the protective layer 12 with the seeds 16 can be manufactured and stored separately until later combined to start germination.

The encapsulating protective layer 12 may also be more effective in preventing premature germination because it may completely isolate or separate the seed 16 from the surrounding medium.

Fig. 3a and 3b show an embodiment of a cartridge 1 equipped with a socket 100.

Figure 3a shows a truncated cone shaped cartridge 1 mounted on a socket 100. The socket 100 comprises a socket opening 102 into which the cartridge 1 can be inserted. The line segment B corresponding to the diameter of the circumscribed circle of the bottom surface 6 is shorter than the length of the socket opening 102. In contrast, the line segment a corresponding to the diameter of the circumscribed circle of the top surface 4 is longer than the length of the socket opening 102. In this way, the truncated-cone (or truncated-pyramid) shape of the cartridge 1 advantageously allows it to be supported by the socket 100.

When fitted to the socket 100, a portion of the cartridge 1 remains over the opening 102. This portion may comprise about 1/10 of the height of the cartridge 1. The portion may additionally or alternatively comprise about 1 mm. The opening 10 in the top surface 4 remains above the opening 102. This is to allow the seedling to grow upward from the opening 10.

Fig. 3b shows another shape of the cartridge 1 also discussed above. The shape comprises two stacked cylinders of different diameters. The diameter of the top cylinder (corresponding to the length of line a in the case of a cylinder) is greater than the diameter of the bottom cylinder (corresponding to the length of line B in the case of a cylinder). Line segment C corresponds to the length of the outlet opening 102. This length is greater than the length of line segment B and less than the length of line segment a. Therefore, the relationship a > C > B applies.

Also shown in fig. 3b is a protective layer 12 placed on top of the cassette recess 10. The protective layer 12 is normally held over the outlet opening 102 when the case 1 is placed inside it. In this case, the depth of the recess 10 need not correspond to the height of the first cylinder, it may be smaller or larger.

A support layer 20 is also shown. The support layer 20 may serve to maintain the integrity of the cartridge and also to separate the portion of the cartridge body 2 protruding above the outlet opening 102 from the surrounding media. This is useful, for example, to avoid algae growth on the cassette 1.

The support layer 20 may also serve to ensure that the cartridge 1 does not become dislodged or disassembled from the outlet opening 102. The support layer 20 may comprise a biodegradable material.

Fig. 4a and 4b show an embodiment of the cartridge 1 and the socket 100. In fig. 4a, the cartridge 1 and the socket 100 are shown side by side. Fig. 4b shows the cartridge 1 fitted in the socket 100.

The receptacle 100 may correspond to a cup for plant growth, such as described in the applicant's patent application EP 3251499a 1. A plurality of such cups may be placed in a plant growing cabinet in which plants may be grown. The box 1 can be placed in any one of the cups 100, and a plurality of different plants can be planted in the plant growth cabinet at the same time.

The socket 100 includes a socket opening 102. Within socket opening 102 is socket cavity 104. When the cartridge 1 is assembled to the socket 100, most of it can be received within the socket cavity 104. The depth of the socket cavity 104 is preferably greater than the height of the portion of the cartridge body 1 within the socket cavity 104. This is to keep the roots of the seedlings and the following plants suspended within the socket cavity 104.

The cartridge 1 preferably fits snugly within the outlet opening 102. In this way, the light reaching the insertion cavity can be strictly limited and the roots of the plants growing in the box 1 are protected from the influence. This is shown in fig. 4b, once the cartridge 1 is inserted into the socket cavity 104, the socket opening 102 is completely covered by the cartridge 1.

The socket 100 also includes a socket channel 106. The socket channel 106 may allow liquid (preferably nutrient liquid) to reach the interior of the opening 102 (i.e. the mouth 104) when the cartridge 1 is mounted to the socket 100. In this way, water and nutrients can still reach the roots of the plants growing in the box 1.
